5. Alarm: The alarm is located above the test button and will sound if the engine's oil pressure falls below
15 psi. In this event, the alarm will emit a pulsating signal. The alarm will also sound if the watertempera-

*6. Water Temperature Gauge: This gauge is graduated in degrees Fahrenheit and is illuminated while the
Key
Switch is turned ON. The engine's normal operating temperature is 170 - 190' F (77 - 88°C).
*7. Oil Pressure Gauge: This gauge is graduated in pounds per square inch (PSI) and is illuminated while
the Key
Switch is turned ON. The engine's normal operating oil pressure ranges between 30 - 60 PSI.
*NOTE: When the engine is manually shut down, and the engine's Key Switch is turned OFF,
the water temperature gauge
will continue to register the last temperature reading indicated
by the gauge before electrical power was turned OFF. The temperature gauge will once again
register the engine's true temperature once
electrical power is restored to the gauge. The oil
pressure gauge will
fall to zero when the engine is manually shut down.
